I've been practicing the Death Posture with great success. I put my body exhaustion. In my mind after getting out of the position is not meant blank, no internal dialogue.
I stand on my tip-toes, stretch my arms out an cup above (sometimes behind my back) my head. as well I hyperventilate.
The internal dialogue goes quiet or tiny voice will be in the mind. The whole point is to quiet the internal dialogue and destroy the ego for temporarily.
I do this as a daily practice. There are many other ways to do the death posture, but the one I do the most successful at. Is one you stand on your tip toes.
